Three beams are each 10 feet long and all of the same size. One is made of wood, another of steel, and the third of concrete. If identical loads are applied to these three beams, which of the following will not happen?

The steel beam will deflect less than the wood beam.

Explanation

The steel beam will deflect less than the wood beam. This choice is not correct since the concrete beam will deflect less than the wood beam—concrete is stiffer than wood.
